This invention relates to wireless communication systems, specifically methods for distributing frequency tones in resource units (RUs) within an 80 MHz bandwidth. The problem addressed is efficient allocation of frequency resources in high-bandwidth wireless networks, particularly when certain frequency subblocks are unavailable or punctured. The invention ensures that frequency tones are distributed across available subblocks to maintain communication efficiency and reliability. The method involves puncturing one frequency subblock within an 80 MHz bandwidth, meaning a portion of the available spectrum is excluded from use. The remaining frequency tones of the RU are then distributed over non-punctured 20 MHz and 40 MHz subblocks within the 80 MHz distribution bandwidth. Alternatively, the tones may be distributed across an entire 80 MHz subblock if no puncturing is required. This approach optimizes resource allocation by avoiding punctured subblocks while ensuring even distribution of frequency tones across the remaining available spectrum.

5. The method of claim 2, wherein the distributed-tone RU does not cross a boundary between two adjacent frequency subblocks.
A method for wireless communication involves allocating distributed-tone resource units (RUs) within a frequency band to avoid crossing boundaries between adjacent frequency subblocks. The frequency band is divided into multiple subblocks, each containing a set of contiguous frequency tones. The method ensures that when assigning distributed-tone RUs, the allocation does not span across the boundary between two adjacent subblocks. This prevents fragmentation and interference at subblock edges, improving spectral efficiency and reducing complexity in resource management. The distributed-tone RUs are allocated within a single subblock, maintaining contiguous frequency allocation within that subblock while allowing for distributed tone spacing. This approach is particularly useful in orthogonal frequency-division multiple access (OFDMA) systems, where efficient resource allocation is critical for supporting multiple users with varying bandwidth requirements. By confining distributed-tone RUs to a single subblock, the method simplifies scheduling and reduces overhead in managing inter-subblock interference. The technique enhances system performance by optimizing resource utilization and minimizing disruptions at subblock boundaries.

This invention relates to wireless communication systems, specifically methods for distributing frequency tones in resource units (RUs) to enable concurrent communication between multiple stations (STAs) within a shared bandwidth. The problem addressed is efficient spectrum utilization in wireless networks where multiple devices must communicate simultaneously without interference. The method involves distributing the frequency tones of an RU over only a portion of the available operational bandwidth, rather than the entire bandwidth. This partial distribution allows one STA to communicate using the distributed-tone RU over the selected portion of the bandwidth while another STA communicates over the full operational bandwidth. By segmenting the bandwidth in this way, the system enables concurrent transmissions without mutual interference, improving spectral efficiency and reducing latency in dense wireless environments. The approach is particularly useful in scenarios where multiple STAs need to share the same frequency resources, such as in Wi-Fi or other wireless local area networks (WLANs).

This invention relates to wireless communication systems, specifically methods for transmitting data using distributed-tone resource units (RUs) in a multi-subblock frequency allocation. The problem addressed is efficient spectrum utilization and interference mitigation in wireless networks, particularly in environments where multiple devices share frequency resources. The method involves transmitting data using a distributed-tone RU, where the RU is divided into multiple frequency subblocks. The transmission occurs over a first frequency subblock and a duplicate of the distributed-tone is simultaneously transmitted over a third frequency subblock, distinct from the first. This duplication enhances reliability and reduces interference by diversifying the transmission path. The distributed-tone RU ensures that data is spread across multiple subcarriers, improving robustness against fading and interference. The technique is particularly useful in orthogonal frequency-division multiple access (OFDMA) systems, where multiple users share the same frequency band. By duplicating the transmission across different subblocks, the method improves signal integrity and reduces the likelihood of data loss due to localized interference or channel impairments. The approach can be applied in various wireless standards, including Wi-Fi and cellular networks, to optimize spectrum usage and enhance communication reliability.
